[sane-devel] mac osx with epson usb backend

[Ricky Charlet]

Howdy,

Thanks for your help!!

So I had:
   Mac OSX 10.2.3
   libusb-0.1.7
   sane-backends-1.0.9
------------------------------
gtk+    1.2.10-10   (via fink)
the apple beta release of x11
sane-frontends-1.0.9
xsane-0.90
gimp  1.2.3-9 (via fink)



BUT!!!!!
from your advice in the previous post, I replaced my sane-backends with 
the sane-backends-2003-01-11 snapshot. (I did a make uninstall; make 
distclean in sane-backends-1.0.9 and compiled then compiled and 
installed the sane-backends snapshot. )

This has solved my problem I reported in my last post. Yeah! scanimage 
now succeeds in recognizing the existance of my scanner.

But I still can't scan. :-(

I'll insert an output dump of scanimage with SANE_DEBUG_USB=255, 
SANE_DEBUG_SANEI_USB=255, SANE_DEBUG_EPSON=255.  My read of this dump 
is that there is a libusb call (usb_bulk_read) failing. But what 
confuses me is that during this dump there are some previous points at 
which usb_bulk_read was called and apparently succeeded.

Anyway here is the dump
=============================

<<I had to delete the dump to get this message past the 40K limit of 
the list processor. I'll leave a bit of what I hope is relevant>>



below is the output of `scanimage`
with the environment vars
SANE_DEBUG_EPSON=255
SANE_DEBUG_USB=255
SANE_DEBUG_SANEI_USB=255
